"Craftsman heavy duty polishing head"

[Branson]

Nah, I don't have a picture, but I found it in a 1953 Craftsman Power Tools catalog.   It's a little rusty, but all intact.  Just have to set it up with a motor and I'm in business.  Holds two wheels and a chuck.  But there's a problem.  The v-belt pulley is in between the sides of the unit, and I can't figure out how to access it to install a new belt.  I've pulled off the two stones and chuck, and loosened the screw in the pulley, but nothing wants to move.  Am I supposed to drive the axle through?  Or what?

Use that segmented stuff that comes apart similar to links in a chain. Not sure what it is called but it talked about it here before.

[turnnut]

yes, we had mentioned it not too long ago.

off of the top of my head, two places to get it are Grizzly's  &  Peachtree Woodworking Supply.

it is called:  "Twist V-Link belt"   ( just google that name)

some of the dealers that sell it, sells by the foot.   I know they make 3/8"  &  1/2"
most common is in orange color.

you can remove or add links as needed for proper tension.

some claim that it will help eliminate belt vibration & friction also.

Trust me, the shaft slides far enough to one side to get the belt on, and you don't want to see the price of Manheim belting.

Someplace there are 2 collars on the shaft.  They do move and the shaft slides.

Yes,  they do cost money, but,

if you are working on many diff. projects, this belt is handy.  it avoids running around
to get diff. size belts.  "one belt fits all"   just add or remove links.

That's what I thought, but I haven't found them yet.  Looks like the shaft goes right into the bronze bushings, and that's all.

I had (now sold) an older Craftsman polishing head, King-Seeley built, with no locating collars; it appears original.  Not sure if the belt was supposed to keep it aligned, or if the flanges were expected to do the job.

Quill on the head pictured is retained by the flanges and possibly the oil cups. 

Pull the wheels and washers off both sides, put the nuts back on to protect the threads, loosen the pully and rap the end of the quill on a piece of hard wood you ain't in love with.
